Abstract
A camera module includes a support structure having an internal space, a movable body disposed in the internal space of the support structure, and a plurality of driving wires supporting the movable body in the internal space of the support structure and configured to move the movable body relative to the support structure, each of the driving wires being made of a shape-memory alloy and having one end connected to the support structure, and another end connected to the movable body. An angle between the movable body and each of the driving wire is maintained at 15.5° or less at all positions to which the movable body is movable by the driving wires.

A camera module comprising:
- a support structure having an internal space;
- a movable body disposed in the internal space of the support structure;
- and
- a plurality of driving wires supporting the movable body in the internal space of the support structure and configured to move the movable body relative to the support structure, each of the driving wires being made of a shape-memory alloy and having one end connected to the support structure, and another end connected to the movable body,
- wherein an angle between the movable body and each of the driving wires is maintained at 15.5° or less at all positions to which the movable body is movable by the driving wires.
A camera module comprising:
- a support structure having an internal space;
- a movable body disposed in the internal space of the support structure;
- a plurality of driving wires supporting the movable body in the internal space of the support structure and configured to move the movable body relative to the support structure, each of the driving wires being made of a shape-memory alloy and having one end connected to the support structure, and another end connected to the movable body;
- and
- a ball disposed between a surface of the support structure and the movable body,
- wherein each of the driving wires is configured to be elongated to move the movable body in one of three axis directions.
A camera module comprising:
- a support structure having an internal space;
- a movable body disposed in the internal space of the support structure;
- a plurality of driving wires supporting the movable body in the internal space of the support structure and configured to move the movable body in a first axis direction and a second axis direction relative to the support structure, each of the driving wires being made of a shape-memory alloy and having one end connected to the support structure, and another end connected to the movable body;
- and
- a ball disposed between a surface of the support structure and the movable body,
- wherein first driving wires of the driving wires are operable to move the movable body only in the first axis direction, and
- second driving wires of the driving wires are operable to move the movable body only in the second axis direction.
